Carmina Gadelica is a compendium of prayers, hymns, charms, incantations, blessings, literary-folkloric poems and songs, proverbs, lexical items, historical anecdotes, natural history observations, and miscellaneous lore gathered in the Gaelic-speaking regions of Scotland between 1860 and 1909. The material was recorded, translated, and reworked by the exciseman and folklorist Alexander Carmichael (1832–1912).
